gine of saving on material and energy. The series engines are small, light. They’re
easy to maintain, and convenient to move. They are used widely as a power for in-
dustrial, agricultural, machinery tool such as irrigation, spray, rice-transplanting,
threshing, grass-cutting, Soil-sampling, and also used in vibration rammer, shock
rammer, marine engine, light-type transport vehicle, movable-type compressor, light-

Please make sure to follow each precaution carefully.
EXHAUST PRECAUTIONS
●Never inhale exhaust gas, it contains car-
bon monoxide, a colorless, odorless and ex-
tremely dangerous gas which can cause un-
consciousness or death.
●Never operate the engine indoors or in a
poorly ventilated area, such as a tunnel or
cave, etc. exercise extreme care when oper-
ating the engine near people or animals.
●Keep the exhaust pipe free of external ob-
jects.
REFUELING PRECARTIONS
●Be sure to stop the engine prior to refuel-
ing.
●Do not overfill the fuel tank.
●If fuel is spilt, wipe it away carefully and
wait until the fuel has dried before starting
the engine.
●When changing oil, make sure that the fuel
cap is secure to prevent spillage.
FIRE PREVENTION
●Do not operate the engine while smoking or near an open
flame.
●Do not use the engine around dry brush, twigs, clothrags,
or other flammable materials.
●Keep the engine at least 3 feet(1 meter) away from build-
ings or other structures.

PROTECTIVE COVER
●Place the protective covers over the rotating
parts. If rotating parts, such as the driving shaft,
pulley, belt, etc. are left exposed, they are
potentially hazardous. To prevent injury, equip
them with protective covers or shrouds.
●Be careful of hot parts.
The muffler and other engine parts become very
hot while the engine is running or just after it has
stopped.
Operate the engine in a safe area and keep
children away from the running engine.
SURROUNDINGS
●Operate the engine on a table, level surface free
of small rocks, loose gravel, etc.
●Operate the engine on a level surface. If the engine is
tilted, fuel spillage may result.
NOTE: Operating the engine at a steep incline may
cause seizure due to improper lubrication even with a
maximum oil level.
●Be careful of fuel spillage when transporting the engine.
Tighten the fuel tank cap securely and close the fuel
strainer cock before transit.
●Do not move the engine while it is in operation.
●If the engine will be transported over a long distance or
on rough roads, drain fuel off from fuel tank to prevent
fuel leakage.
PRE-OPERATION CHECKS
●Carefully check fuel pipes and joints for
looseness and fuel leakage.
Leaked fuel creates a potentially dangerous
situation.
●Check bolts and nuts for looseness.
A loose bolt or nut may cause serious engine
trouble.
●Check the engine oil and refill if necessary.
●Check the fuel level and refill if necessary.
Take care not to overfill the tank.
●Wear snug fitting working clothes when operating the
engine.
●Loose aprons, towels, belt, etc., may be caught in the
engine or driving train causing a dangerous situation.

1-2 Overall Dimension and Installation
1-2.1 overall and installation dimensions
1-2.2 Installation
(1) There must be a tight stationary foundation for diesel engine to avoid vibration or
movement when the engine is running.
(2) Be sure that the center position of output axle is correct.
(3) Check whether calibration between axle hole of belt wheel and keyway shaft is
correct and whether the tighten screw nut of belt wheel is tightened up.
(4) when the engine is matched with other belt-driving machine, the diameter of driv-
ing wheel must be in harmony with the speed of diesel engine and the size of axle
wheel of the equipped machine. Otherwise it will directly influence working condition
of diesel engine, the life of the engine and the efficiency of working machine.
The diameter of driving wheel (belt wheel) can be calculated as follow:
Diameter of engine driving
wheel=
Diameter of axle wheel of working machine×speed of working
machine
Diesel speed
(5) Be sure that belt is tightened properly.
If the belt is fixed too tight, the engine will be overloaded while starting, the belt will
be drawn longer, and the engine may be damaged.
If the belt is fixed too loose, the belt will slip at high speed and high load.
